Retired Hawks head Dr Godfrey Lebeya has told the Madlanga Commission that he approved a request by KwaZulu-Natal Hawks head General Sonona for DPCI members to undergo polygraph tests. Lebeya says Sonona submitted the request as the provincial head, with the tests accommodated under DPCI directives and employment processes. However, the commission questioned why Sonona made the request while two separate investigations into the theft had already been commissioned. Sonona had also been responsible for the keys to the safe where the drugs were stolen, although Lebeya says he was unaware of this at the time.
